Objective To evaluate the risk factors of treatment outcomes in MDR-PTB patients with long-term treatment regimen in China. Methods 332 patients with MDR-PTB were recruited from 22 sentinel hospitals and 1 tertiary general hospital in 23 Provinces in China from January 2013 to December 2017. The treatment outcomes were investigated retrospectively, and the influencing factors of treatment outcomes were collected and analyzed. Results For the 332 patients, 196 cases were successful (59.04%), 76 cases failed (22.89%), 33 cases lost follow-up (9.94%), 12 cases died (3.61%), and 15 cases were transferred out (4.52%). The main factors affecting the outcome of treatment included age ≥50 years (OR=0.342, 95%CI 0.169-0.690), course of MDR-PTB ≥1 year (OR=0.297, 95%CI 0.108-0.815), irregular treatment (OR=0.429, 95%CI 0.197-0.934), cavities before treatment (OR=0.073, 95%CI 0.026-0.207) and positive sputum culture month 3 (OR=0.161, 95%CI 0.072-0.358), and cavity closure month 6 (OR=15.723, 95%CI 5.690-43.444) is predictor of success. Conclusions The result of this study indicated that age, course of MDR-PTB, irregular treatment, sputum culture in month 3, cavity before treatment and cavity closure in month 6 were the influencing factors of MDR-PTB outcome. In the initial stage of treatment of MDR-PTB patients, sputum culture results in month 3 and CT images have important predictive value for the treatment results of MDR-PTB patients.
